Shuhei Yoshida president of Sony's Worldwide Studios was in attendance at DICE Summit this week and discussed various industry topics.
Shuhei Yoshida was a panel speaker at DICE Summit 2015, which took place this week. IGN, was in attendance and reported some of his quotes.
According to Yoshida, sequels didn't always have the reputation they have now as solid earners. They were even seen as wasted expenses that often don't generate a return on the same level of the original games.
Later on however things changed when sequels became less risky and marketing teams realised they could annualise game releases. This became an issue as games got more complex and took longer to make.
Yoshida added that marketing executives, not understanding how game development works, would look at franchises like Call of Duty and Assassin's Creed as a way to prove annual releases work well financially. Yoshida went to say that with all due respect to developers of major franchises he "hates" annualised releases and wish they wouldn't happen.
